System and method for treating plastic preforms with air conveyor or transport shuttle

Abstract

The invention relates to a system (1) for treating plastic preforms (5), comprising an injection-moulding machine (10) for producing the plastic preforms, a sterile blow-moulding machine (20) for shaping the plastic preforms (5) into plastic containers, and a transport system (30) for transporting the produced plastic preforms (5), at least partially or in sections, from the injection-moulding machine (10) to the blow-moulding machine (20), wherein, during transportation, the plastic preforms can be guided in particular to an outlet region for the plastic preforms (5). According to the invention, the transport system (30) comprises a sterile air conveyor (30) or a plurality of transport shuttles (30), in particular magnet shuttles, and the plastic preforms are transported from the injection-moulding machine (10) to the blow-moulding machine (20) by the sterile air conveyor or magnet shuttles.

Description

technical field [0001] The present invention relates to systems and methods for processing plastic preforms. Background technique [0002] It is known to produce plastic pre-forms by means of an injection molding machine and then form the plastic pre-forms into plastic containers in a blow molding machine by means of a stretch blow molding process and / or a blow molding process. [0003] In the prior art, preform production (injection molding process) is usually not linked (link) with container production (stretch blow molding process, blow molding process), so that these processes are usually separated from each other both in position and in chronological order ( Local and chronological separation). After the preforms are produced, they are usually stored as bulk goods, separated again by a sorting device before or at the time of container production and then supplied to the blow molding machine. Therefore, after production, the plastic preforms first need to be temporaril...

AI Technical Summary

Problems solved by technology

The separation of the injection molding machine and the blow molding machine from each other in terms of location and time sequence leads to an increase in the effort required to form the container from the preform, because before the start of the blow molding process, additional transport routes, additional storage, and Resterilization and heating of preforms

[0005] Furthermore, it is known from the prior art that conventional sorting devices for sorting or aligning plastic pre-forms present as bulk goods before entering the blow molding machine are prone to failure
